To all vwhom t may concern:

Be it knoivn that. l, CHARLES C. Hon", a citizen of the United States, residing at Fremont, in the county oi Dodge and State of Nebraska, have invented new and useful lm- Which the following is a specification.

Vehicles equipped with headlights require highways to be properlyYY illuminated to avoid' accidents and when traveling through' the streets or' cities and other thickly settled districts, such headlights are required to be dimmed in order to prevent the blinding glare from seriously aiiecting pedestrians, horses, andthe drivers of vehicles generally. The present invention has relation to means under the control of the driver Whereby the blinding glare of the headlights may be overcome without entirely cutting oil the light, thereby enabling the operator to avoid any objectionable glare and at the same time shedding suiiicient light to preventa driver from colliding With the vehicle.

The invention consists of a. shutter pivotallv mounted and actuating nieans whereby 'such shutter may be thrownout of the vvay or in positionto dim the light and prevent the blinding glare which under certain conditions is objectionable.

The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated and claimed.

In the; drawings hereto attached :e-lligure l is top plan view showing the invention applied to the head lamps of a. motor vehicle such as an automobile. Fig@ is a vertical central longitudinal section of one of the head lamps, the full lines'showing the shutter elevated and the dotted lines indi` cating the position of the shutter when dropped to dim the light. 1digs. 3 and i are views similar to Fig. 2 of .modifications Fig. 5 is an enlarged sectional detail showing the connection between the rod and shntter and illustrating the relation of the parts when the shutter is moved so as to rest upon the lamp. F ig. 6 is a View ot' theparts shown in Fig. 5 illnstrating the relation of the elements when the shutter is inoved to obstruct the light.

Corresponding and like parts are referred to in the following description, and indicated in all the vievvs oi the drawings, bv the saaie reference characters.

I '-Zhe numeral l des: such as gene ally prec vehicle of the anton lamps are generally eq ..illnniinators which cast bodies or casings of the being-provided with highly polished rotors for throwing the rays of iight to an able distance in advance or the very shutter 2 is pivctallv mounted so as to be thrown upwardly out of the Wav or dorvnwardly to intercept the rays ci light thereby prevent the objectionable hliz'iding glare. shaft 3 which is journaled to the lmnp. The rod or shaft 3 is formed .v'l' a crank portion or arin l and a rod or lil'A connects the crank por ion or arni 1 oot-ooerated lever 6 which is arran veniemly to be engaged hv the foot e. operator. Y Movement ot' the lever in direction throws the shutter downward indicated by the dotted lines vsherebjr rays of light are intercepted and the blinding glare overcome` The shutter is so disthe lamps ile typ-e. These ipped with strong il upon a instor- Tlie shutter i2 is attached to a rod or' .linding light, the

posed and ot' such relative lengthas not to shutter is located in advance o' the light. Fig. 3 shows an arrange ne t n which the rod or shalt 3 is locatw in the re of the light andbetween the light and tl reflector. ln this case, the shutter L) when lowered intercepts the rays ot light which would otherwise be thr'vvn rorivarr; liv the reiiector therebj; preventing the gl:

ln Fig. l the nod is located in tie front of the lamp andA above the same, and the shutter 2 is arranged to drop in front of the lamp or to fold upon the saine as indicated by 'the dotted and full lines.

In each of the modifications, a shutter supporting rod or shaft is adapted to be operated by means of a foot-controlled le-v ver in the manner stated herein.

From the foregoing description` taken in connection With the accompanying drawings, the advantages of the construction and ot the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and'while 'I Ihave described thel principle of operation of the invention, together with the device which I now Consider' to he the 'nest embodiment thereof` I desire to have it understood that the device shown 1s merely illustrative.y and that such changes may be made when desired as are within the scope of the invention Aas claimed.

Inasmuch as. provision must be had for, a greater movement of the shutter than the crank iu the modification illustrated in Fig.

4. the knuckle of the shutter is formed with a slot i' in which a pin 8 projecting from the rod or shaft 3 is arranged to operate.

' The slot 7 extends about one-fourth of the circumference of the knuckle so that. While the crank or arm 4 has a movement ,of about 150C. the shutter has an approxunate movey.ment of 270. This is obvious from the full zuid dotted lines .of Fig. 4. Upon turning the rod or shaft 3 to move the crank from ter will drop into the position indicated in Fig. 6 and by the dotted lines in Fig. Jr.

IVhen the crank or arm il is moved from 3o the position shown in Fig. 6 to the position indicated in Fig. 5, the shutter '2 is carried past the vertical and drops into the position indicated in Figs. 4 and 5.

Having thus described the invention, .y

what is claimed as new is The combination with` the headlamp of a vehicle, of a shutter comprisinga knuckle along oneedge thereof having a through slot extendingtransversely of one side th ere- V40 of, a' shaft passing through and adapted to turn Within said knuckle andpro'vided with an operating arm, and a pin projecting' from said shaft and passingthrough the slot formed in the knuckle of the shut'- 45 ter, the arrangement specified permitting the shutter to move through' a greater arc--. than the shaft. In testimony whereof I atix my sign. ture in presence of two witnesses.
